Be it known that I, MALCOLM W. LONG, a

citizen of the United States, residing at Harrisburg, in" the county ofDauphinand State ing the target-shaft. crank thereof to the.

- ver 6.

of Pennsylvania, have invented certain new and useful Improvements inSwitch-Stands,

of which the fo lowing isa full, clear-,and exact description,referencbeing had to the accompanying drawings, of which Figure 1 is-aplan view of a well-known type of switch-stand, partially broken away,in whichmy. invention is embodied. Fig. 2 is a sectional side elevation.v

The object of this invention-is to provide in a switch-stand a readymeansfor attachswitch-connecting rod, whereb when said rod and crank areconnected an the said rod is secured in'place to a switch the said rodcannot be detached from the crank.

To this end the invention consists in pro-. viding the crank of aswitch-stand of wellknown type with an upwardly-extending stud or.crank-pin, which pin is adapted to be entered into a correspondingverticalhole through the end portion 6f the usu'alswitchconnecting rod,and providing said rod with a lug or rojection which when said rod is.

connecte in place to the switch will-be under and close y adjacent theunder side. of a partof the frame or casing of'the switchstand, in whichposition said rod cannot bea segment-gear 3, which engages a bevelpinion4 on a horizontal shaftb, which carries the usual weighted operating armor le- On the lower end of the target-shaft 2, below the casing, is acrank 7, (in this instance double, as seen, so as to be adapted foreither aright-hand or a left-hand switch,) having extending upwardlytherefrom a stud or pin Specification of Letters Patent.

9 is the switch-connecting rod, the outer D endof which is connected tothe switch (not shown) 'in the customary way, the inner, end of whichrod is rovided witha vertical hole 10, adapted .to t the stud-or 8 0fthe tar- The under side'of the casing- 1 of the stand is in thisinstance undereutto forman L- shaped space in vertical -cross-section, Y(marked 11 in Fig. 2,) the roof or'top of 'WhlCll space'is of a heightabove the top of the crankpin'8 sufficient to permit the inner end ofthe switch-connecting rodto beplaced upon or detached from the pin 8when the crank is in the proper position that is, the height of saidspace 11 above the pin 8, is greater than the thickness of the inner endof the said rod.

Said space. 11 is of a horizontal depth from the line of the center ofthe pin 8 (when the stand parts are in osition shown in'zthedrawings-that is, w en the switch is 0 en) to the vertical wall 11-thereof .sli greater than the horizontal thickness 6 theswitch-connecting rod from the axis of the hole 10 therethrough to itsouter side. A

The rod 9' is rovided witha'lug or projection 12 extendinglongitudinallyirom the inner end of' the rod, whichlug is of such lengththat when the rod is. connected to the switch landlthe stand in positionin which tly the switch is open-that is,.in the position ofextreme'throw in one direction, as shown in the drawings-said lug willextend under the casing 1.,thereby preventing any possibility.

.of disengagement of the rod 9 from the crank-pin 8.

In assemblingthe parts therod 9 before it is connected to the switch isbrought to the position gindicated by dotted lines in thedrawings'-that'is,'parallelwith the trackway and with the wall 11 ofthes ace 11, and so with the lug" 1 2 freei Sai dropped into place, withits hole 10 engaging the'pin 8, and is then turned-on its pivot (the pin8) to the'position of the full lines and the outer'end'thereof securedto; the switch in the usual way, it of course being understood that thetarget-shaft crank 7- and other parts of the stated are during thisassembling opera- 8, the upper free end of which when the tar- 1 tion inthe position of extreme throw in one get-shaft is rotated in theoperation of the I direction 'to bring the pin" 8 beneath the rod istheir ICOv . Patent 1. In a switch-stand of the character recited, thecombination with the target-shaft, of the crank thereon, having theupwardlyprcjecting crank-pin, the switch-connecting rod having a holeadapted to receive said crank-pin, and having the projection on itsinner end, and the casing havlng a portion under which said projectionis adapted to extend when said rod is connected to the switch, and to befreed from said portion when the rod is disconnected from the switch andsuitably rotated on said crank-pin, substantially as set forth.

2. In a switch-stand of the character recited, the combination of thetarget-shaft, of

the crank thereon, having the upwardlyprojecting crankin, theswitch-connectin rod having a 110i; adapted t9 receive said crank-pin,and having the rejection on its inner end, and the casing raving aortion under which said projection is adapte to extend when said rod isconnected to the switch, and having also the undercut space the heightof the roof of which space abovethe top of said crank-pin is greaterthan the thickness ofthe inner end of said rod, whereby when said rod isdisconnected from the switch and rotated on said crank-pin to cause saidprojection to come under said space, the said rod may be disconnectedfrom said crank-pin, substantially as set forth.

In testimony whereof I have hereunto aiiixed my signature.
